Due to the drawbacks of Norwegian couplers, the Indonesian State Railways adopted the Janney couplers starting in 1951. [note 3] [4] To allow interoperability with the older rolling stock equipped with Norwegian couplers, early Janney couplers would have gap which allowed the use of Norwegian coupler adaptor called "Perdijk" device.

AAR couplers on 1,000 mm (3 ft 3 + 3 ⁄ 8 in) metre gauge [7] and some passenger (FIAT 7131 DMUs) and freight rolling stock on standard and broad gauge. Small knuckle coupler with slot in knuckle for link and pin couplers on 750 mm ( 2 ft 5 + 1 ⁄ 2 in )
By default, the output value is rounded to adjust its precision to match that of the input. An input such as 1234 is interpreted as 1234 ± 0.5, while 1200 is interpreted as 1200 ± 50, and the output value is displayed accordingly, taking into account the scale factor used in the conversion.
The Norwegian coupler is found only on narrow gauge railways of 1,067 mm (3 ft 6 in), 1,000 mm (3 ft 3 + 3 ⁄ 8 in) or less in Great Britain and its former colonies. For example, it is used on the Isle of Man Railway , the Western Australian Government Railways , in Tanzania , on the Ffestiniog Railway , on the Lynton and Barnstaple Railway ...
